  31 /**
  32  * Public EGL API entrypoints
  33  *
  34  * Generally, we use the EGLDisplay parameter as a key to lookup the
  35  * appropriate device driver handle, then jump though the driver's
  36  * dispatch table to handle the function.
  37  *
  38  * That allows us the option of supporting multiple, simultaneous,
  39  * heterogeneous hardware devices in the future.
  40  *
  41  * The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
  42  * opaque handles. Internal objects are linked to a display to
  43  * create the handles.
  44  *
  45  * For each public API entry point, the opaque handles are looked up
  46  * before being dispatched to the drivers.  When it fails to look up
  47  * a handle, one of
  48  *
  49  * EGL_BAD_DISPLAY
  50  * EGL_BAD_CONFIG
  51  * EGL_BAD_CONTEXT
  52  * EGL_BAD_SURFACE
  53  * EGL_BAD_SCREEN_MESA
  54  * EGL_BAD_MODE_MESA
  55  *
  56  * is generated and the driver function is not called. An
  57  * uninitialized EGLDisplay has no driver associated with it. When
  58  * such display is detected,
  59  *
  60  * EGL_NOT_INITIALIZED
  61  *
  62  * is generated.
  63  *
  64  * Some of the entry points use current display, context, or surface
  65  * implicitly.  For such entry points, the implicit objects are also
  66  * checked before calling the driver function.  Other than the
  67  * errors listed above,
  68  *
  69  * EGL_BAD_CURRENT_SURFACE
  70  *
  71  * may also be generated.
  72  *
  73  * Notes on naming conventions:
  74  *
  75  * eglFooBar    - public EGL function
  76  * EGL_FOO_BAR  - public EGL token
  77  * EGLDatatype  - public EGL datatype
  78  *
  79  * _eglFooBar   - private EGL function
  80  * _EGLDatatype - private EGL datatype, typedef'd struct
  81  * _egl_struct  - private EGL struct, non-typedef'd
  82  *
